MECH's have taken over and the Guardian's have been dispersed. Mellea, who was finally coming to terms with being a bride to a Successor and finding her place with Leo, has been taken to a secret, underground location by her father. Mellea wakes up to an unknown world, her father has been turned into a MECH, but is trying to fight against the MECH woman who rose up against the Guardians, she calls herself Doctor. The Doctor has connections to the Guardians and has found a way to neutralize their powers. While in the underground facility one of the MECH's is trying to help by creating a serum to return the powers to the Guardians. Mellea must get the serum to the Guardians and make them believe in themselves enough to save their land and the people who look up to them.

An exciting, fast-paced sequel to Bound; I couldn't wait to see what happened after the cliffhanger! Mellea came into her own in Divided, finding strength within herself.Even though she wanted to do nothing more than escape from the Tower walls before, now she is doing everything within her power to restore the Guardians and herself to the Tower once more. Luckily, Mellea's water pendant survived with her, and she finds out that she can do amazing things with it. I enjoyed getting to learn more about the Guardian faith, Livolism, as Mellea develops her powers. Once Mellea finds the rest of the Guardian's and is reunited with Leo, Mellea becomes responsible for helping them realize that they must fight the MECH's. Drama unfolds as family ties within the MECH world are revealed. It was nice to learn the backstory behind many of the Guardians and their brides; Leo's history is revealed, helping to crack some of his outer shell. What I liked most is that Mellea and Leo are still working on their relationship through most of the story, no insta-love for them and no worries of a love triangle. I can't wait to see what happens next!
